About
At SEMA Construction, Inc. (SEMA), we believe every project begins with people. Our work with Native Nations across the United States reflects our deep respect for sovereignty, cultural heritage, and community vision. We proudly partner with Tribal governments and enrolled citizens to build infrastructure that strengthens communities, supports local economies, and stands the test of time.
Empowering Native Nations Through Infrastructure
SEMA empowers Native Nations through infrastructure by building trust-based partnerships that honor sovereignty, cultural heritage, and community priorities. Through collaborative project delivery, such as CM/GC models, SEMA delivers durable, cost-effective solutions that support economic growth, mobility, and self-determination. From transit hubs to waterlines and community centers, each project is tailored to reflect Tribal values and advance long-term resilience.
More Than Builders — Partners in Purpose
Every relationship starts with listening. Our approach on Tribal land is rooted in humility, collaboration, and respect. We work closely with each Nation to understand priorities, build trust, and deliver infrastructure that reflects shared goals. Our work on Tribal lands is guided by humility and respect. We build relationships first, learning from each Nation's history and leadership. Together, we deliver projects that reflect shared values and advance long-term community goals.
We understand the legal, cultural, and operational frameworks unique to Native Nations.
From navigating Tribal Employment Rights Ordinance (TERO) requirements to aligning with federal and grant funding sources, our team ensures compliance, transparency, and efficiency at every step. This experience allows us to avoid delays, maximize resources, and deliver real value to the communities we serve
Long-term partnerships with Tribal leaders and community stakeholders
SEMA builds lasting relationships by showing up with consistency, respect, and accountability. We prioritize local voices, elevate Tribal leadership in the decision-making process, and engage community members throughout the project lifecycle. Our repeat work with several Nations is a testament to the trust and impact we aim to build—not just the infrastructure.
Flexible delivery models tailored to the unique needs of each Nation
No two Nations—and no two projects—are the same. SEMA adapts our delivery methods to best support Tribal goals, timelines, and budgets. Whether through CM/GC, design-build, or other collaborative models, we prioritize alignment, transparency, and responsiveness to community input, ensuring that each project reflects local values and long-term purpose.
